I wanted to enable dismemberments in my JK2 with g_saberrealisticcombat 20. I typed that in but nothing happened. So I thought it's because of the German version and I downloaded the English demo. I typed again g_saberrealisticcombat 20 into the console, but now it worked! It also works in the Jedi Academy demo (which is German, too and for JA there it is g_sabermorerealistic). What's my problem, why can't I dismember in my full Jedi Outcast?

you first have to allow cheats (which I'm sure you know, but just in case type in: devmapall) then if I remember correctly, it only goes up to 5... but I just started playing again yesterday after 4 years or so, so I may be wrong; but I don't think I am.
